The bolivar, like Venezuelaâs economy, is trapped in a downward spiral. Within Venezuela the effects of the economic chaos are seen at the supermarket, where empty shelves are a constant reminder of the economic dysfunction that has come to define South Americaâs fifth largest economy.
In optics, chromatic aberration (CA, also called achromatism, chromatic distortion, and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.n some circumstances it is possible to correct some of the effects of chromatic aberration in digital post-processing. However, in real-world circumstances, chromatic aberration results in permanent loss of some image detail.
It accordingly becomes possible to correct the chromatic aberration of one glass by superadding that of another. The false colouring of the image is due to chromatic aberration. The double concave lens is added to correct for chromatic aberration.
